Good idea.

Are you interesting in standardizing the format of such a configuration
file? I think we should, and been thinking about it on and off for about
a year. The snow-fort.org package.scm files are a reasonable starting
point. Chicken egg files contain somewhat similar information.

The library name (C @v1.0.1) is almost equivalent to the R6RS-style
library name (C (1 0 1)) or (C (v1.0.1)).

IMHO the optimum solution would be to:

- extend the R7RS rules to permit a list as the last library name part
to give the version number

- extend the R6RS rules to permit non-negative exact integers as library
name parts; and to permit symbols in addition to integers in the version
number part
